Upgrade 7.14.6 to 8.7.1

[Background_Pitch5281]

I’m trying to upgrade my SuiteCRM instance and the upgrade fails at the legacy-post-upgrade step. I am performing steps on Windows, also have tried on Linux.

Command I ran

php ./bin/console suitecrm:app:upgrade-finalize

It asks for the version, I enter:

8.7.1

Then I get:

step: legacy-post-upgrade | status: failed
Unexpected error running Legacy Post Upgrade

SuiteCRM Log Error

Here’s the exact error from suitecrm.log:

Fri Nov 14 11:19:05 2025 [36440][1][ERROR] convert: Conversion of 11/14/2025 11:19am from Y-m-d H:i:s to m/d/Y failed

Environment

• SuiteCRM version before upgrade: 7.14.6
• Target version: 8.7.1
• PHP version: 8.2.26
• Database: MySQL (8.0.43)
• Server: WAMP on Windows

I believe you have the wrong version. It should be 8.9.1

I have installed the 8.7.1 migration package. I also tried it with the 8.9.0 and 8.9.1 migration packages, but I am getting the same error with all of them.

Conversion of 2018-08-04 23:44:59 from user format d/m/Y h:ia failed

I am getting the following error hundreds of times in my suitelog. Wed Sep 26 12:43:02 2018 [12817][1][ERROR] fromUser: Conversion of 2018-08-04 23:44:59 from user format d/m/Y h:ia failed The locale and user are both configured as d/m/Y and 11:20pm. I am using Suitecrm 7.10.7. Any ideas why ?

Date conversion issue

For some reason I can’t get the call popup to work. The error that shows up is as follows: convert: Conversion of 09/09/2016 17:30 from Y-m-d H:i:s to d/m/Y H:i failed. there are no other errors I have checked the file permissions but I still get this error. I have noticed that when setting up the call information it seems to reflect correctly on the screen but not when it is suppose to popup anyone know what could be happening

Conversion of 2018-08-04 23:44:59 from user format d/m/Y h:ia failed

I tried this fix but now get a slightly different error: convert: Conversion of 19/05/2021 15:46 from Y-m-d H:i:s to d/m/Y H:i failed followed immediately by: fromUser: Conversion of from user format d/m/Y H:i failed Any idea what needs changed here to resolve?
